The current product is built around one idea: you should never have to write a reply from scratch. On Gmail, Auto-Drafts can prepare responses as mail arrives, so suggestions are waiting in the compose window — and in the Gmail mobile app — for you to review. A one-click AI Reply button appears in WhatsApp Web, LinkedIn, Outlook, Slack and Zoho Mail, and a keyboard shortcut (Ctrl+Shift+K) triggers it in any other text box on the web. The system pulls from up to five sources when composing: the live conversation, your historical emails, your saved writing style and tone, facts from your linked website or help centre, and current information from the web. That means replies can include real prices, policies and delivery details rather than generic filler. You choose which underlying model to use among GPT, Claude and Gemini family options, depending on your plan. Beyond replies, the extension also acts as a general assistant: it can summarise or answer questions about the page you are on, proofread and fix grammar in selected text, rephrase, translate, and accept voice input spoken in any language. The vendor reports more than 500,000 users and roughly 1,300 Chrome Web Store ratings, and states that user data is not sold, not used for AI training, and encrypted in transit over TLS 1.2 or higher. **Pricing & Plans:** Free plan with 15 AI responses per month and no credit card. Elite is $18/month billed monthly for Gmail Auto-Drafts, about 1,000 advanced responses and PDF/image attachments. Ultra is $39/month for about 2,500 advanced responses and priority support, with yearly billing offering a discount. Teams can be billed together, and you can supply your own API key. - **Gmail Auto-Drafts:** Drafts replies inside Gmail as messages arrive, so they are ready to review and send — including from the Gmail mobile app. Nothing is sent automatically. - **AI Reply across platforms:** A one-click reply button inside Gmail, WhatsApp Web, LinkedIn, Outlook, Slack and Zoho Mail, plus a Ctrl+Shift+K shortcut for any other web text box. - **Learns your style and business facts:** Builds replies from your sent emails, your saved writing styles, and the prices, policies and links on your linked website or help centre. - **Choice of leading AI models:** Switch between GPT, Claude and Gemini family models depending on plan, with fast models remaining available after the advanced quota is used. - **Page and text utilities:** Summarise or question any page, correct grammar, improve clarity, rephrase, translate any text, and dictate prompts with voice input in any language. **Strengths:** Works inside the reply box of Gmail, WhatsApp Web, LinkedIn, Outlook, Slack and Zoho Mail, not in a separate window; Can ground replies in your own website and help centre so facts and prices are correct; Never sends anything automatically — you always review and send; Free plan with 15 monthly responses and a web app on mobile, with an option to use your own API key **Limitations:** Gmail Auto-Drafts are limited to Gmail; other platforms only get the one-click reply button; Higher advanced-response quotas are tied to the $18 and $39 monthly plans; The AI Reply button requires a Chromium-style desktop browser, so full functionality is not available on mobile browsers [Profile (Markdown)](https://openaitools.app/tool/chatgpt-writer.md) ## ForthWrite ForthWrite is an AI writing assistant aimed at people who live in their inbox. Instead of asking you to learn a new tool, it installs as a Gmail and Outlook web extension and adds a drafting widget directly to the compose box. On first use it analyses emails you have already sent to build a voice profile, so the very first suggested reply starts close to something you would actually send. The model is tuned for nuance and can also take a manual persona prompt when you want a specific register. The product family spans three levels. Inbox is the individual product, with a free tier that provides 10 AI drafts a week plus voice matching, and a Pro tier that unlocks auto-drafting, batch drafting of long threads, a Prompt Lab for versioning and A/B testing prompts, recipient- and intent-aware drafting, voice dictation, smart retrieval over your past mail, and performance analytics. Teams extends Pro drafting to every seat in an organisation with a shared voice baseline, a shared prompt library, a team analytics dashboard, and a review record showing what was drafted, what changed, and which model produced it. ForthWrite also sells consulting to professional-services firms such as accounting, tax, advisory, lending, and brokerage practices. Those engagements begin with a free 30-minute diagnostic and can extend into a paid audit, a 30-60 day roadmap, and implementation with written SOPs. The company is clear about its operating principle: ForthWrite drafts, and a person sends, so accountability and signature stay with the user. **Pricing & Plans:** Freemium with a free forever tier (10 drafts per week, voice matching, no card required), Pro at $24/month billed annually ($29 monthly), and Teams from $59/seat/month billed annually ($79 monthly, 2-seat minimum). All paid plans start with a 14-day free trial; Teams gets a 30-day trial. An optional Bring Your Own API Key mode takes roughly 17% off. Consulting is scoped separately per firm. - **Voice matching from your sent mail:** ForthWrite reads emails you have already sent to build a voice profile, then refreshes it roughly every 50 captured emails so drafts keep tracking how your writing evolves. - **Auto-draft and batch drafting:** Pro users can have replies waiting when they open Gmail, and clear dozens of threads in parallel instead of writing each one by hand. - **Recipient- and intent-aware drafting:** Drafts adapt tone to the person you are replying to and treat follow-ups, intros, and status updates as genuinely different jobs rather than one generic template. - **Prompt Lab and performance analytics:** Version control and A/B test your prompts, then track acceptance rate, voice match, and intent mix on a measurable improvement curve. - **Team standards and compliance guardrails:** On Teams, a shared voice baseline and shared prompt library keep every seat consistent, and a draft that breaks a firm rule stops the preparer with a written reason. **Strengths:** Drafts pick up your real tone because the voice profile is built from mail you have already sent; Works inside Gmail and Outlook web with no migration or new inbox to learn; Strong free tier with 10 drafts a week and voice matching included, no card required; Teams adds shared prompts, team analytics, and a review record that firms usually need **Limitations:** Web-based Gmail and Outlook only; there is no full desktop client experience; Full value depends on having a decent history of previously sent emails for the voice profile; Consulting engagements are custom-scoped, so pricing is not published [Profile (Markdown)](https://openaitools.app/tool/forthwrite.md) ## Frequently Asked Questions ### How do Jetwriter AI (formerly ChatGPT Writer) and ForthWrite compare in monthly traffic?
